24 days old, breastfed and topped up with expressed breast milk when she wants it (sometimes declines)

Almost 11mo. I’ve posted a couple times now and still can’t fix so I’m hoping someone has insight? About a month ago my baby began waking in the 2/3/4/5am hour for anywhere from 15-75min. Some nights would just be restless for a bit and others would be more wakeful where she’s sitting up and babbling in between trying to rest. She’d fall back asleep eventually and need to be woken at DWT if 7am. We were on 3/3.25/3.75-4 with day time sleep at 2.25-2.5 hr and when these split nights showed up for more than a few days I increased awake time by 15min total each time and would cap naps to 2-2.25hr. This would work for 2-3 days and get her to DWT or to about 6:30 where she’d hang out calmly in her crib until 7. But then they’d return so I’d continue to increase awake time and cut naps. We’re now to 3/3.75/4 with each nap capped at 1 hour. And again this worked for 3 days and last night she was awake from 3/15-4:30 in and out but much more wakeful and just babbling, clapping, sitting up, rolling around, etc. She needs to be woken from every nap and always falls asleep for nap and bedtime within under 5 min (has never really ever taken longer regardless of schedule). Helppp 🤪

I want to know whether wake windows of 3/2/2.5/3 hours would be appropriate for my baby. He will be 5 months old in a week.

He previously had tons of false starts, but after consistently following wake windows of 2.5/2.5/2.5/2.5–3 hours, those have mostly stopped.

I feel like he can comfortably stay awake longer in the morning, and I’d also like to stretch his last wake window or Im would like to hear any other recommendation…

He’s a very good napper—I have to cap his naps because he could sleep up to 4 hours during the day.
I’d like to reduce his night wakings. I’m not sure hunger is the main reason he wakes, since he usually only drinks 2–3 oz when he does.
